You’ve got a few options. “On the way” would be the Sand Lake Rd Target near Florida Mall, but it’s not a Super. Kind of dinky. There’s a couple bigger ones farther north past Universal, but those would be out of the way.
Your best bets may be the Super Targets on 192. There’s one near Vineland (aka Apopka-Vineland) which is convenient if you’re taking the south road out of the airport (FL-417). You can also go west past WDW on 192 to the Super Target by FL-429. It’s a pretty nice Target geared towards vacationers (souvenirs, groceries, etc) and it’s less than 10 minutes from the World Dr main entrance to Disney.
